Abstract

The invention discloses a planing wheel device of a coal crusher. The planing wheel device of the coal crusher comprises a hollow cylindrical fixed sleeve, wherein the outer side wall of the fixed sleeve is provided with an annular planing wall; and the planing wall is provided with a first isolation transverse groove array consisting of first isolation transverse grooves along the axial direction of the fixed sleeve, and a second isolation transverse groove array consisting of second isolation transverse grooves along the circumferential direction of the fixed sleeve. According to the planing wheel device of the coal crusher disclosed by the invention, the first isolation transverse groove array and the second isolation transverse groove array on the planing wall are utilized, so that a small amount of sticking coal dust can be precipitated into the isolation transverse grooves in the running process of a planing wheel, the planing wall is isolated and protected, hard stones in the coal dust are prevented from excessively wearing the planing wall in a harmful way, and the service life of the planing wheel of the coal crusher is prolonged greatly. The planing wheel device of the coal crusher is simple in structure, and has high practicability.

Description

technical field [0001] The present invention relates to a coal mining equipment, more precisely, a planer wheel device of a coal crusher. Background technique [0002] The alias of coal crusher is also called double-stage crusher, which belongs to high-efficiency fine crushing equipment, mainly for the crushing of coal, and refines coal into coal particles or coal powder according to actual needs. The planing wheel of the existing coal crusher adopts the continuous planing teeth arranged on the smooth surface, and the hard stones in the pulverized coal are very easy to cause damage to the smooth surface, and the wear is relatively large. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing a planer wheel device of a coal crusher. [0004] Above-mentioned technical problem of the present invention is mainly solved by following technical scheme: [0005] A planer device of a coal crusher, the pla...
